Field testing of the Stryker STR-1 was performed both with CO2 and with compressed air from a high-output Crossfire compressed air system.

As with any paintgun, velocity adjustment is a critical safety step. It must be performed at the start of each game day.

Adjustment of the velocity was performed with hex-wrench, turning the velocity adjuster clockwise for an increase, and counterclockwise for a decrease. While velocity was easy to adjust with the included CO2 cartridge, the marker was not well suited for use with compressed air.

On compressed air, the highest velocity achieved with the adjuster turned to its maximum was 274 feet per second.

It was also discovered during test firing, the the STR-1 did not perform well with a Vlocity forced feed loader. When used with a Boosted VLocity loader the marker broke paintballs in its breech as frequently as one in ten shots.

Switching to the unpowered hopper that was included with the player's pack resulted in noticably improved feed performance, making possible strings of 20 or more shots without a break. Surprisingly, although the hopper was not powered, jamming was not a significant problem. It appeared that excess gas driven up the feedneck was helping to agitate the paintballs.
